Hi People, I am writing a web app on LAMP. The app is sort of yellow pages where people can login and post advertisments with pictures. App needs to allow users to upload pictures. (jpg and gif), needs to create thumbnails of those pictures and to store thumbnails and full pictures. App needs to manage all those files - can be as much as 20K plus images. I think image file size, file type and image dimensions restrictions should be easy to handle by using $_FILES array and getimagesize function. The issues that I am thinking of and need suggestions about are 1) Storage and retrieval - File system sounds like a better choice over database. We are talking about 20 thousand plus pictures. 2) Thumbnails - Should I create those once and save it in a file when the image is uploaded for the first time. Looks like a faster option than creating them every time on the fly. 3) Security issues - I believe I must have a world writable "666" permissions directory to keep images as users of the web app are uploading them. Does that create any security holes in my application? 4) Any thing else related to image uploads that one might need to take care of. Are there any tutorials on image upload issues. Thanks and HAND.
