I'm coding an image gallery to use on my PHP site and need a bit of help with a couple of features I want to code into it. I was hoping someone here could either give me some pointers or send me to a website that will help with either explainations or code snippets :)
1. Firstly, thumbnails. I have created an admin panel where I upload the images and can set various things like the category, title etc, and all that is stored in a MySql database, and the file uploaded to a general directory. But i'd also like to create a thumbnail of the image as it uploads. I've found several scripts that make thumbnails from images already in a directory, but i'd like it to happen as I upload the image. Is that possible? Without having to use some all-in-one image gallery script heh. I'd also need it to resize the image proportionally so that images aren't just squashed into a 100x100 square shape.
2. Secondly, I'd like to "tag" images like with LJ entries, so that on the front end when a picture is being viewed, the list of tags is shown and can be clicked on to show other image thumbnails with the same tag. But i'm not really sure how to go about this... I was just going to have a table field called img_tags and store them all in that per image, but then is that efficient? searching for matches within a db field? any tips or suggestions?
3. oh and as an extra thought, how can i then take those tags and make a tag cloud maybe?
All and any help would be most appreciated! :)
