Problem with image-column and PDF with JPG images

We are using Sybase ASE on Win NT.
(Adaptive Server Enterprise/ 11096 ESD 1/NT (IX86)/OS
4.0/2008/32bit/OPT/Wed May 07 01:29:40 2003)

and are using jconnect to store PDF files in an image-column:

create table blobstore
    blobid              INT not null,
    document  image  null,
    lastsaved  datetime null,
    primary key (blobid)

We are having no problems with storing and retrieving PDF files WITHOUT
embedded JPG images.

But when we include JPG images in the PDF file, the retrieved PDF file
from the database has been corrupted.   The file has the same
size, but when we compare the two files (before and after
being stored in the database), some of the values in the binary stream
have changed, namely 0x81, 0x8d, 0x8f, 0x90, 0x9d.   All these values have
been changed to 0x3f.    The PDF file can be viewed in Acrobat Reader,
but with no images.

Any clues ?

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...

Image in image
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? AlaN As a try, what happens if you boot either to PXE ...

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?  ...

Hello. I have an asp:image, and i want it to get its image url from a stylesheet.
