Ya, I checked the MIGweb site and his 3 lies of code. In principal very useful, but the [img] one isnt working here... because of, erm what AZ said. Have you tried any other forums with the same code? If it aint working for others then you will have to ditch that guy as a webspace source and go get the blueyonder stuff.
You can use the paint program that comes with windows to resize jpegs if you dont have any other program. Most other peeps would probably say Photoshop, however legitimate copies of this cost £££. There are free paint/image editing programs available, but you would have to google for some and try them out - unless anyone else can offer suggestions?
You could swap to linux and use the free gimp paint program
I'm sure blueyonder must do some webspace? I'll let some of the cable peeps answer that one, though the info you need is usually hidden on the 'help' pages of the isp in question.
