how can I cache a small part of image in flutter? - image

How I can show the image in the app like the social network?
My meaning is I show a blurred preview of the image (not download completely) then if the user clicks on the image, app downloading the image completely and shows.

iOS XCode launch screen storyboard does not display image from asset catalog when running on device

I'm running into an issue where an iOS app project using Launch Storyboard does not display some images from the asset catalog. But it can display another image in the same image view. This tells me that the image view is set up correctly, and something is wrong with the image itself
How can I understand why my image is not displayed on launch screen when starting app?
I checked the asset catalog membership, and the images are members of the correct target. The image displays in the interface builder preview.
I checked and images are not displayed when saved in either JPG or PNG format.
The image previews fine on Storyboard preview.
I tried using smaller image, so it doesn't seem to be a file size issue.
Does not work on either device or simulator.
This image displays:

Not able to open thumb-nail image on mobile device

Website
I am using a Magento website which is not able to open the thumb-nail images on the mobile devices. I changed the css file for different resolutions inside the media block but still not able to open the images.
The images inside the red square are not opening in the mobile devices. Whenever i click on any of those images nothing happens.
The image are opening in the desktop for all size of display.
Is it happening because of wrong css code or some other reasons.
Your resolution for that size add proper image width and height in CSS.

I have a background image that is loading only partially

I have a background image that loads mostly, but half of the time there is a pice missing from the image and you have to refresh the page to get the entire image to show. Could the image I'm using be corrupt or broken? Or could the problem be somewhere else. I am using a mac and google chrome.

iOS Loss of image quality and resolution

I have and imageview that i use throughout my app. It can hold a picture from the gallery or from the camera.
In the end I upload it to a webserver using php.
But where does xcode downscale my image? Ipad pictures are aprox. 300x300px.
Tried downloading a 1000+ x 1000+ pixels image, but it looks like it gets downscaled once i open it trough uiimagepicker. In my gallery its fine before i start my app, but when i add it via my gallery its low res.
I need these images with the resolution they were made with.
Is there any way to obtatain that?

PHP Image Upload Resize, Watermark, Title & Copyright Info

Ive written an image upload and resize script for my website which allows users to upload images, and then the script resizes the images in 3 different sizes and adds a watermark image (my website logo) on the top.
The problem I have is, that if a user then tries to upload one of the resized photos again, it will then add the logo watermark on top of it again.
What I want is to maybe add some information to the uploaded image (i.e. author, which I could set to my website name), so that if a user uploads an image which has already been watermarked, I can put a check in my script so that I dont add the watermark logo again.
Is this possible with PHP?
Take a look at this http://www.php.net/manual/en/function.iptcembed.php
