So the users pick an image from their desktop using a standard html form then when they submit the form there is php code that resizes the image then saves it down to a folder on my hosted webspace then a mysql table is updated with the relevant image detail like the file location etc. I have a 1Mb size restriction on the images and i've noticed that when i upload smaller images the time taken is pretty short. Any guidance on handling image sizes? I guess if users keep uploading 1Mb images my site is going to get slow in terms of displaying those images?
