Improve jpeg qulaity
Discussion
I have submitted a jpeg image to a marketing company for transferring to t-shirts and they have asked me to improve the detail and send the file as a pdf. Of course I can do the latter easily enough - it is the former that I am unable to do. Can anyone help / tell me how to go about it? I don't have photoshop and my Mac refuses to install DeTopaz....
Grateful for any help! Thank you.

It was originally a 3MB jpeg file from which the background was professionally removed, reducing it to a 783KB file. I then applied some Picasa special effects ('neon', to be precise) which increased the size to 800KB. It's the 'neon' effect we're trying to have printed on to t-shirts. I've tried applying the 'neon' effect to the original file but it's impossible to remove all of the background with the tools I have....
without seeing the original file it is impossible to be accurate, but I'd say that going from a 3mb JPEG to a 783kb JPEG means that the image was cropped. 783kb is pretty small (depending on the compression rate used when saving) so it won't produce decent image if you are trying to reproduce it large. It will likely appear pixelated.
Can you post up the original and your Neon version somewhere and I'll have a look.

3mb file is tiny, 780kb file is very, very tiny. You need to have a proper size file to start with to get anywhere with this.. I sent off a 34mb file today for print, Just to give you an idea.... size matters - not for web, but when it comes to print.
Ah yes, I know you're right. However, I have to make do with what is available to me [sigh]...GetCarter said:

Well, it depends on the compression used and the size you actually want to reproduce at...I can create vector-based print quality A3-sized adverts that are less than half a mb, or have billboard-sized photo images that run into hundreds of mb.
In this instance, the JPEG is roughly 21 x 12cm @ 300ppi which I would have thought ample for T-shirt printing purposes (unless it is going to wrap around the entire body/T-shirt)
The 3MB photo was from a Panasonic Lumix DMZ-TZ3...
Many thanks Colin for your help. The t-shirt printers should be able to do something more than adequate with the pdfs you created for me. I'll try to remember to post a picture of the result!
For curiosity's sake, this is the original photo (reduced to allow posting).
