Re: [PHP] Graph Question..
Jim, on the calling page change echo p align=\center\image src=\$graphname\/p\n; to echo p align=\center\a href=\$graphname\something here/a/p\n; Now, when you click on the link, the error message should show instead of the broken box.

Re: [PHP] Graph Question..
Jim, Regarding undefined function: imagegif(), It could be that your build of the GD Library doesn't include gif support. You can try replacing this function with imagejpg() or imagepng(). Imagepng() will likely be faster and sharper than imagejpg().

RE: [PHP] Graph Question..
What I'm wondering is if you are calling the graphic's placing into the page correctly. I believe the class will probably work. I have a page that includes a graph that I generate using mySQL and PHP. This is the code I use to actually display the graphic (not what generates it). ImageJPEG($pic,$graphname); echo p align=\center\image src=\$graphname\/p\n; Of course there is a significant amount of code that actually generates $pic, but this is what I had to do to make the graphic appear.
