In a support manner I can give you resolutions to common issues but you would be doing these yourself on your server.
Your issue you reported is fixed you can now upload large images because your using imagemagick I just uploaded a 1.82mb image fine
Your issue is your using displayimage to display the photo and there is an issue. Have you replaced the files as I instructed?
Remember we do not speak arabic so it is hard to really navigate your admin panel and set stuff.
Works fine if you dont try to watermark images with a bad watermark
