Hi,

I want to have images of my members cars, and have them displayed as a fixed watermark on the first and second alternating color.

I already have an image their now, but would like to have random Images......

can someone tell me how to do this?

Thanks
Derek

the poor man's way to do this is to write an uploader that will generate the filenames like: userid_photonumber.jpg (10034_3.jpg), where "photonumber" autoincrements with every upload by that user.

create some heavy queries that determines the largest photonumber for that user.

generate a random number with "photonumber" as the high end. rand(1,$photonumber);

then, in your templates, use an img tag with a URL like this:
/path/to/photos/$post[userid]_$randomnumber.jpg
