HTML Image Issue

[czardas 1,061]

Hi Folks. I know that this is sightly off topic, but I thought somebody here might be able to help. I have recently started learning HTML and I wish to embed music transcriptions into my pages. When I put images of written music on a web page, some of the horizontal and vertical lines dissapear. Adjusting the size of the image produces different effects in different browsers. If I thicken the lines then they appear uneven. All in all, it turns a very proffesional image into a mess. Perhaps gif and jpg images are not suitable for this purpose, or perhaps I need some different software to prepare the images in some way. Does anybody have any suggestions?

Can I add another tag or something?

Sorry guys, wrong forum. I think the problem is the percent part. Never mind!
