Photo Question / help required

Hello Everyone

am trying to get a web site up and running to maybe get my pens out there a bit more

but iv hit a problem that is proving to be a bit of a head ache (for me anyway)

i want to load a photo of my pens onto the home page of my site but it wont load up

the web developer tells me that the image is too big and that i have to resize the image into a smaller size 292pixels X 219 pixels

what ever that means to get it to load.

i was imformed that i needed a program like photo shop to do it

ok easy, i down loaded a trial version of photo shop, and yep do you think i can work it out.nope.

so if there is someone out there that could help me out with info on how to do this it would be greatly appreciated

please bear in mind i am only a simple miner who blowes stuff up for a living so not real tech/ computer smart. no Phd etc:no:

thanks in advance for any feed back

cheers Tony
