JPEG image over Tranparent Image problem

I am just started my career as a developer few months back  and I am in my first project and I am struck. Please help.
I am developing  a website with and C#

In one of the web page, in an Image control, I have to display an image over an other image which I sucessfully did with various code articles help from the web. Now, in one scenario I have to place a smaller image first. Then over that I have to place a gif image(in which there is a circle transparent area). It is something like placing a photo in a photoframe. With some help from the web, I am able to display the gif image as transparent. But using Graphics.DrawImage when I combine the bottom image and then the gif image, the combined image comes out as a bad quality picture. Can anyone help on how to achieve something like a photo inside a photo frame, photo inside a clock. Pls pls help.

By your ideas, I think you can save the combined image with JPEG format. And the effect is very perfect.

You can get a bad quality when you save a GIF image with GDI+. The reason is that GDI+ use halftone to processing GIF image. So you must create a color palette by yourself to save your image.

Thanks for your email and trusting me.

Thanks for your reply.

I tried it. But as soon as I place the jpg with the transparent gif, the combined pictures gets worse quality.
I really needs the top image to be transparent gif because if take an example of clock, the middle area where the time is getting displayed has to be transparent except the three needles(hour needle, minute needle, seconds needle) and the jpg image has to be filled in the transparent area in such a way that the three needles will be over it. I really got confused. Can you pls help me if possible with some code??

Image on Image
I am trying to display a page that has image of a map on it. The user can then place other images of red thumbtacks on the image at different locations. Then when these thumb tacks are clicked on, they open a folder of pics related to the area. I saw a method in the imageButton class that returns the (x,y) of the location where the user clicked. I thought I could use this information to place another, smaller image button, on that area. My problem is that i can't seem to get the bottom imageButton to be transparent so I can see the smaller one. Am i on the right track with this. Any advi...

Hi, I have a project where clients viewing my website can buy t-shirts. They can choose from a number of t-shirt colors and shapes which are their plain colour. They can also choose a number of prints to be placed on the t-shirt. These will be graphics stored in a database. My problem is on how I can displaty the t-shirt with the graphics or logo they chose on te t-shirt. It would be something like drawing text on an image but instead drawing an existing image on the base image. Any Ideas? (I am using visual studio 2005 and vb.NET)   RegardsMerovingian you 1.

Imaging, but not imaging
We multicasted to 43 machines. Updated the image on the master. Multicasted the updated image to 36 machines. (the other 7 wouldn't join the session for some unknown reason). I visually verified that all 36 were imaging. One of the 8 which didn't rename appears to not even have been imaged. The problems with the previous image were still there. It's as though the machine didn't image even though I saw it take part in the session and the temp bar going across the screen. What the heck's going on here?

Problems with a thumbnail image to popup Full-size image (image paths from a database)
I am hoping to get more feedback from entering this in perhaps a more appropriate forum.   Please refer to post   I think I’ve explained what I would like to do but can’t figure out how to successfully code it.   I found it interesting that if I removed the Onclick event, my Bind error goes away.   And changing the Bind to an Eval traded the Bind error for a parser error.   How can I pass the path of the Full size image from my DB to the javascript so that ASP and Java both are OK with the coding?  ...

How (and when) is an image cached for an ASPX with ContentType = image/jpeg ?
I have a page 'GetImage.aspx' which takes 3 query string parameters: ID, Height, and Width. It uses the ID to retrieve binary image data from the database then scales the image to the given height and width. The content type for the page is set to "image/jpeg" so I can use this page as the url for an <img> tag or ImageButton control. Examples: <asp:ImageButton id="img" runat="server" ImageUrl="GetImage.aspx?ID=12345&Height=120&Width=200" /><img src=
