What is today a proper file sze limit when letting users upload images. The images will be resized but don't know what a good limit would be.
Depends on the final use of the image, server resources available, type of images and expected tech level of your users.
example: If you're expecting lots of images uploaded directly from digital photos then your limit will be in the 5M to 10M range. Most users will take images directly off their cameras and not attempt to resize before uploading to a website.
It really boils down to the questions I started with.
