I want to make a wallpaper changer because windows high compresses the the image so you see artifacts even if already use a jpeg or even a really high quality png or bmp.
I know what I need to do for all of it I just need to know how to save an image to a jpeg without it being compressed. I have tried using the encoderparamters and getcodecinfo aswell as setting the quality to 100 but I still get a really bad looking image in the end.
Is there a way where I can save an image to a jpeg without getting the crappy image quality like with visual basic?

I have a routine that creates a report which includes text and graphics. When I print to a PDF or printer the output looks great. When I draw the report on an image to save as a PNG, GIF, JPEG, etc. it does not look as good and I understand that is related to the 96 dpi native resolution. However, I made some modifications, and even though the graphics part of the image looks better, the text does not look as good as the PDF. I am creating the image using 300 dpi and text rendering is set at the highest quality.

I am trying to create a wpf program that allows the user to create custom shapes or pick premade shapes and that after making their selection, a canvas shows their shapes randomly sized, positioned, colored and copied in multiples. I am hoping that on click, the program will put its output on a time interval and that the user can click stop when they are satisfied with how everything looks. My issue is, I would like to also give the user an option to save their created artwork as a jpeg file. Also if I wanted to link this file to a web browser what will I have to do?

The images on my e-commerce website are watermarked with an aspx script, therefore when you are browsing products, if you want to save the image it saves it as aspx rather than jpg or png. The thing is I need to give urls of jpg for a website that advertises products. There are more than 10,000 products so I can't save all of them manually, so I made a page with jquery that get's the image part of the product display page. What this page returns is this:
<div id="result"><div id="loadpic" style="width: 160px;">
<img border="0" src="http://11.11.11.11/img/picsel.aspx?code=IPHONE-32GB-4">
</div></div>
And the output is only an image. How can I return this image not as an aspx page but as a jpg or png? Since there's a script for watermarking the image and making it aspx, shouldn't there be a reverse function?
