I KNOW it's not the best program to use but it's all I have here in Portugal (Photodraw) :).

When I create Jpegs I get a shadowy effect around it ?

it is like small speckles around the image and I can't seem to get rid of it :(

when I create GIFs the quality is terrible :(

does anyone know why?

I really could do with some advice, even if I have to use a different program.

Thanks in advance as always.

If you need to see them I can sticky you a URL with one of the images.

:)

Can't give you specific advice on your images but if you're looking for a new graphics package. Heres one for free (open source)

[gimp.org...]

Probably doesn't do gif's due to licensing issues.

diddlydazz-

Sounds like your compression is set too high on your jpegs. That generally causes the halo effect and blurry edges. Also, if you have large areas of a solid color, you may get lots of speckling and splotches around edges with .jpegs. For example - a jpeg with a white background is NOT going to look the same as your web page's white background 90% of the time. It'll always be just a little off. Get into large areas of reds and blues - and you'll see it turn ugly real fast.

The very nature of jpegs is not of crystal clarity when used for web work - rather it is to handle a multitude of colors with reduced file size. Oftentimes, you'll get better results with a .gif - just depends on the image you are working with. Jpegs are best used on mutli-colored images, whereas .gifs can handle the large solid area colors better, though the number of colors is limited. That's where working with color palettes comes in.

Setting a palette, if you can, may help resolve some problems you may be having with areas of solid color, even in jpegs. You can tweak and poke and probably get better results than you are getting now.

There's gotta be a way to sneak a copy of Photoshop or Paint Shop Pro to where you live, isn't there? Paint Shop Pro has trial downloads from many locations across the net and is a very nice program with a small price tag. I've even done magazine ads with it. If you become familiar with it- you'll be surprised what magic you can do.

Thanks for the link I have looked and you are right you can't use GIFs, but thanks anyway.

I am downloading a trial version of paint shop pro as I write this post.

Thanks both for all your help.

dazz- The JPEG yckiness you're describing is often referred to as "artifacts" One way to somewhat reduce the appearance of artifacts is to reduce the level of compression, as idiotgirl suggested... another way is to apply a slight blur to the image before compressing it.

I've heard great things about a program called Pegasus JPEG Wizard, which is available via download, that allows you to put different levels of compression on different areas of an image... you could apply a higher level of compression to the more complicated areas of a photo, and apply almost no compression to that big expanse of blue sky (or white wall, etc.) that gets icky looking when compressed. (I'd try it myself, but they don't offer a Mac version... grumble)
