Magento Caching Custom Images - performance

I am using the avalanche theme and make use of the homepage slider.
The images are added to the site via a section in the admin panel and they are stored in
media/banners/default/slidex.jpg
I notice that these images are not being cached and loaded directly from their location. Is there any way to include images such as these in the magento image cache in order to reduce load time?
As these are large banner images you would expect them to take longer to load, however in the pingdom tools analysis for my home page it indicates that the server side wait is much longer than the time it actually takes to receive the files.

I had a similar problem witch was caching a resized brand logo slider images.
I solved the problem by storing the resized images in media/product/cache/resized_images - with Mage::getBaseDir('media'). So, you just need to check if the cached image exists before regenerating it.
Everything in this folder is deleted when flushing image cache in admin.
I hope it helps.

Static images loads really slow

So, my assets folder in Angular app has a size of about 1GB where images are close to 134MB and a video of 738 MB. A component which displays these images take about 3-4 seconds to render in local, and it takes more than a minute on a application which is deployed to PCF(even after using AOT).
Strange thing is that the components renders just in fraction of
seconds if we revisit it.
I have tried using lazy loading for images by using deferload. But,
still the problem not resolved.
Could someone share their thoughts on this.
Mostlikely fetching such big images causes the app to load slow.
It is probably unnecessary to have such big image size. You could try to resize the images with something like lambda resize image.
Also if you revisit the site all the data is already cached in the browser. You could try to disable cache in the network tab and it should be slow on every visit of the site
You can use npm install package ng-lazyload-image
Fine the url for description and usage docs

images on home page overlap on load

Images on my home page overlap on load and also the it takes more time to load. Iam using magento 1.9.
I had used Litespeed_LiteMage magento extension to speed up my site load time but still there is no change.
I am still getting overlap images on page load.
How can I overcome this overlap issue
Mostpropably it is an error in your CSS. But there can be a lot of reasons why images overlap... maybe you can post a link here?

Meteor JS image upload and display

I'm trying to build a E-commerce site with a admin page where the administrator can upload images of certain products.
I'd like Meteor to upload those images to a folder and then display those images in the product page of that product.
I know that normally the image files that the client will be using should be inside the 'public' folder, but I'd like to know more about what other options I might have.
Also, if I upload a new file to the 'public' folder or if I delete a file in the 'public' folder, the website refreshes itself...and this is good and bad at the same time depending on what effect you are after....
Here are my questions:
What if I create a 'uploads' folder in the server and upload the images to that folder. Would it be possible to display the images inside the 'uploads' folder in the client browser??? How??
Is there a way to use the browser to access the contents of the 'public' folder???
Is there a way to stop the 'reactivity' of the site if changes happen in the 'uploads' folder created?
Is uploading the images to the 'public' folder the best solution available to this problem?
Thank you very much for the help
When dealing with what will likely be a large number of images I like to offload not only the storage but also the processing to a third party.
My go-to app in this situation would be Cloudinary. Here's why:
Storage - I can store the original images outside of my application. A huge benefit to keep images in sync from dev to prod.
CDN - I get the extra benefits of images being quickly loaded from the Cloudinary CDN.
Off-load Processing - All of the processing of images is handled by Cloudinary which doesn't slow down my app as a whole.
Image Manipulation - I can make calls to the original image, calls to just get a thumbnail, and calls to change manipulate, ie :effect => grayscale. So if a 1000x1000px image was uploaded, I can request a 50x50px from Cloudinary that will return the image cropped to that exact size rather than using CSS to shrink a huge image.
Flexibility - I can change the size of images and return that exact size to the app without having to re-upload images. For example, if my product page pulled in thumbs at 40px, I could easily make a call to grab the same image at 50px.
Hope this helps.

You can do all of this using the meteor package collectionFS. The package is well documented and you have a variety of options that you can uses for storing the uploaded files. CollectionFS also gives the ability for image manipulation on the upload, such as creating a resized thumbnail.
I realized this question is a bit old.
I had the same problem, one of the solution that works for me is using meteor-upload https://github.com/tomitrescak/meteor-tomi-upload-jquery
Definitely don't store stuff in the public directory - it will slow down starting up the app, and hot code refreshes on image upload could easily cause it to crash once there are a decent number of images in there.
Any of the above solutions with storing images elsewhere would work. One other option is using the peerlibrary:aws-sdk package to upload stuff to S3, which is what I use for several apps and have found to be very clean.
Storing the image as a base64 string in MongoDB is also a method. Useful for posting to APIs and save the worry of having to handle other 3rd Parties.

Where does magento store its cached images?

I know that magento resizes the original product images and caches it multiple times with different sizes according to its need.
Where are those chached images stored (path)?
Are they the ones that will get deleted when you flush image cache from cache management?
If I were to manually cache some images, where would I have to put them in order for them to get deleted when you clear cache from cache management?
Thanks :)
All cached images saved in BaseUrl/media/catalog/product/cache folder
Yes
Checkout the BaseUrl/media/catalog/product/cache folder you will get your answer
The answer here is resized images are already saved separately to the normal cache, in media/catalog/product/cache not in var/cache/.
If you look in System > Cache Management you will see there is a separate button for clearing just those images, so if you really need to clear image cache use that button.

Drupal 7.14 image upload unstable

I am setting up a site in Drupal 7 for a photographer which includes uploading a large number of photos to the server. My problem is that image upload is extremely unstable. Sometimes it works, sometimes it does not. It seems I am hitting some kind of memory or bandwidth limit, but I don't get any errors.
I created a custom content type for photo albums, with each category (e.g. "portrait", "wedding" etc.) as a node with a number of attached images that I display using views slideshow. Everything works on the front end.
Image upload is handled by an image field and the Media file selector widget. The problem is that sometimes during upload the page will just refresh and the image does not show up in the list of attached images.
I also tried using the Plupload widget that allows uploading several images at once. With this I get a slightly different behavior. The images will "break" after two or three images meaning that they show up as corrupted images with part of the image missing. Sometimes refreshing the page or clearing all Drupal caches will allow me to upload maybe four images at once.
It looks like this
What is strange is that the same exact image file will sometimes upload, and sometimes not.
I am not uploading huge images. They are all manually resized to less than 1600x1600px before uploading, with file sizes between 200 and 600 KB.
Drupal 7.14
Plupload library 1.5.4
Plupload integration module 7.x-1.0
Plupload widget 7.x-1.0-alpha1
PHP settings:
PHP version 5.3.10
Max upload size: 5M
Memory limit: 1024M (increased from 128M using ini_set() in settings.php)
Any help will be greatly appreciated! I have been googling for days trying to solve this.
