So, for my wordpress mobile site, there is a button to upload an image (either from camera or phone gallery).
However since the size of mobile images are well over 3 MB, it takes too long to upload them.
Is there a way to reduce the image size before the upload even happens? or to speed up the uploading process.
Thank you guys!
Yes, you have some solutions:
Compress image before send; open image in your graphic editor and save as JPEG or PNG with lower quality; file will be <3MB
Upgrade your home internet - upload parameter is important here
Upgrade your server plan - maybe you can have better network connection.
You can't make it faster by changing the code or something.

I am developing an android app, where I require to upload image/video files really quick. What could be the best approach to do the same? I am using windows azure media server.
I researched and went through the entire documentation on Azure yet couldn't find the right solution for the below problems. So, I am elaborating the list of issues and scenarios for your understanding.
Just to add top-up on this issue. Following are the scenarios.
We are uploading the video through app. - Need help is optimising the upload transfer rate by using viable compression.
As of now it is taking approximately 1-2 mins to complete the upload.
Post uploading the Video we crop the video using FFmpeg codecs in our application on VM and then move the video file to Blob Storage.
Followed by that we use the Azure Media SDK to make an asset to encode the cropped video for adaptive streaming and we also create the Progressive Download file for downloading the video which is cropped and has stiched images with it.
Cropped and Unstichhed video is played in the app which is of max length 32 seconds.
This still shows the buffering on the 4G network which is questionable?
Downloadable file which has images stiched with it comes out with noise in the bottom of the video. (Attached image for ref.) Ref. Image. Look at the right botton pixelation.
Our Xamarin forms app supports both Android and IOS. This app uses a lot of png images on each and every screen.
We are looking for a better approach to deal with it. Whether to download a zip of png images and maintain them locally (or) download each png image on demand and cache it. It's ok if the application takes bit more time at the time of login. Could you please suggest.
In my image editing application i am providing two option to the user, 1) save image to Media library and another share it through ShareMediaTask. The issue i am facing is while saving the image to library the size of the image is 1.5 mb. If i share the same image through ShareMediaTask(Gmail / Hotmail etc) The size of the image reduces to 330 Kb. Hence it affects the quality of the image. How i can share the same image in Media library without losing the size and quality in windows phone 8.
I also tried the same share through library (ie without using my application). Still the result is same.
If anyone had a solution to this issue please update your suggestions.
Thanks,

The email application automatically downscales images, there is no way to control this. An alternative solution would be to, eg, upload the image to Skydrive and email the link.
Does anyone know why sometimes when you right click on an image in a browser (IE, FF or Chrome), and save the image on your hard drive, you get a different file size image and lower quality than the original image you uploaded to the server? This happens even if you clear the browser cache.
What is strange is that it doesn't happen all the time. What is stranger is that I wrote a simple html page with a link to the image. I right clicked on the link and saved the target image. It saved it with the original size and quality. However, a little later, I tried saving the same image again, the same exact way, I got the lower quality image with the reduced file size.
I know it's not an issue with my PC because the same thing happens on my phone (Droid X) browser. When I save an image into its memory from the browser, it is lower quality and reduced file size.
The lower quality image file size is usually a little bigger than half of the original image file size.
What is going on?
UPDATE AND ANSWER:
My problem was caused by Verizon Wireless compressing images through its network: http://www.macobserver.com/tmo/article/verizon_starts_data_throttling_content_optimization/
I was occasionally tethering using a MiFi device and was apparently in the top 5% of bandwidth users. Therefore, images downloaded through the MiFi into my laptop and on my Droid X were being compressed through the network. The browser was caching the "bad" images, so they appeared compressed even when I was on a different network, making it harder to for me to troubleshoot what the heck was going on. I hope my answer helps others.
I don't want to get credit for my own answer, so I am changing this to a different question: Since a lot of people use such wireless networks now on their mobile phones and through tethering, should web developers test their sites for such use to account for the image loss? Sometimes the image loss is considerable. If so, how do we do it if this occurs only during certain periods of the month for only certain users? What compression algorithm are they using? Can we emulate the compression?
My problem was caused by Verizon Wireless compressing images through its network (see the edit to my question). This problem no longer exists with newer devices (or perhaps Verizon has abandoned this practice).
I have to write a J2ME app to retrieve images from server and display in mobile phone.
I have seen and test that Snaptu have a mechanism to cache image, event with 100 images (both normal size and zoom size). I wonder how they can do that?
I though that those guys use rms to save image stream to data. But when i check in working folder of simulater( I use Windows XP and Sun Wireless Toolkit 3.0, the Emulator device i use to run my program is CLDC Device 1 - my working folder is C:\Document And Settings\Administrator\javame-sdk\3.0\work\6\appdb), i see some .db file. When i delete these files, i still can view cache image in my emulator????
I also thought that those guys use heap memory to save image. But it is not correct because when i set limit device memory is 2MB (like some mobile phones), and i load and view 100 images in zoom size, it didn't make OutOfMemory Error?
It so weird.
Any one can help me? Thanks
RMS is possible solution for trusted and untrusted MIDlet.
JSR-75 file connection is possible solution for trusted MIDlet only. You can't create file if your app is untrusted.
