Everytime I do a large image in Photoshop and convert it to jpg, it gets all messed up and pixelated.. And i want it to look like it does in photoshop..

I've tryed putting image data quality up to 10 but it just makes it load slower.

can anyone help me?

Thanks to those who respond

Here's a little crash-course but if you want accurate and quick answer on the subject, try to read about compression formats (specificaly for image).

JPG is one of them but usually leaves artefacts behind. It makes the files really light compared to the perfect quality photoshop image you were refering to.
It's a price to pay but general rule is the more precision/detail/quality, the bigger the file thus the slower to load. It's up to you to balance the two when you save as in JPG format.

Oh one last thing.. I'm assuming you solely wanted to put those files on the net, right ?
If so, keep in mind that the resolution of the image doesn't needs to exceede 72 dpi. If you want to print and what's not, that's another story.
Always keep a high-res copy of your work.
I shut up now !

what kind of images is it?
piantings with lots of colour, or 'cellshaded' stuff, ie few clean colorfields?
the nature of jpeg-compression makes it suitable for paintings and photos but bad for 'cellshaded'. It can't handle the crisp borders between the fields very well. if this is the case, i recommend you use the gif-format instead.
