I use a digital camera to get the pictures on my computer. But the pictures always come out around 650 KB. IM trying to make them smaller but have no clue how. Ive seen people post like 7 pics and I can only post one at a time. Oh and when I post it on a form when and you click on my post the picture comes out HUGE and BLURRY. Well if anybody could help that be great! Thanks!!

Example:

-----
Buy Them......Raise Them.....Breed Them.....Hatch Them.....And If you want to..... sell them

What do you mean blurry...this picture is excellent, if you look at the head, it is very sharp. Sure the body is a bit blurred but the important is that the head is clear. The blurring of the body is caused by optical laws that control the "depth of field". Whether it is a film or a digital camera, a picture can only be in focus over a certain distance, past that distance it becomes blurred (for example everything between 50 cm from the lens to 70 cm from the lens will be sharp, those 20 cm of sharpness is the depth of field. Any object located closer than 50 cm or further than 70cm from the lens will be out of focus). Many factors change the depth of field but to simplify, the more magnification you try to get, the narrower the depth of field. The closer you are to the subject (using macro lenses or zoom), the smaller the depth of field, to a point where it is impossible to have the entire snake within that "sharp" distance, hence blurring of the parts of the body that are closer or further away...A quick rule for animal photography is that the head and especially the eyes are within the depth of field, because it is often the center of attention...and this photo is perfect for that, the blurred of the body does not distract from the quality of the picture...There are a couple of things you can do to try to increase the depth of field (but you can never get rid of it) take the photo from further away and decreasing the zoom (but then the snake will be much smaller in the picture) or you can increase the amount of light, with more light available, the camera will close the diaphragm, which increases the depth of field. You can also override the camera controls to close the diaphragm and decreases the speed...

As far as size of the picture is concerned, some camera have different settings to control the quality of the picture (low, normal, high). The higher the quality, the larger the file. Low quality is certainly good enough for a computer screen and the net. high quality is used if you intend to enlarge it and get it professionally printed. You can also change it after the fact using a picture editting software either by decreasing the size of the picture or by decreasing its quality or a combination of both. There are plenty of photo editting software available and pretty much all of them would be able to do that...(PS you can decrease the quality of a picture with software but you can never increase the quality...)

hope this helps
