What paint/photo editing software do you have on your PC? Even the most basic lets you save photos in B&W, and in other formats.

If it's something you want in a hurry, just post your pic as an attachment and I'll convert it here

Irfanview will do it. Freeware.

Each time you save a jpg you lose quality, where as with TIF you don't. But TIF are much bigger files.

Exactly so having saved it as a jpeg you have already lost quality - saving it back to a tid won;t magically regain the quality.

Thanks for that - wanted to post the same link, but couldn't for the life of me remember the name of that piece of software in the wee hours of the morning last night :D

Thought it might be useful to explain (in very simple terms) some of the differences between image types. Tif (or tiff) images are very akin to RAW images as they come out of a camera. They are generally very big files. We deal with these big files by compressing them in various ways. These different ways produce jpg, gif and png files to name the 3 most common compression types used in the graphic arts. In the compression to produce a jpg (or jpeg) file there is a loss of some information due to the compression algorithm (instructions) but the file size produced is relatively small for complex images such as photographs. Both gif and png files are no-loss compression methods but for a photograph, the files are generally larger (though still much smaller than a tif or raw image. However for graphic images where you have large areas of a single colour (such as map or diagram), the gif or png would be smaller than a jpg of the same image. The other relevant issue is colour. Gif images are limited to 256 colours which is ok for most graphical images but not photographs. Jpg and png files support 'true colour' (16.7 million colours) and is often referred to as 24 bit colour.

first thanks every one it is now done
apart from the quality side i have access to a sticker printer and tif files are easyer to use on it due to no background
