Thank you for contacting LEADTOOLS. I believe you are trying to display the images in the client's browser using an IMG tag If this is the case, you will need to have a page that loads the J2K image usign LEADTOOLS and saves a JPEG to a memory stream that you can return using Response.BinaryWrite()

To load the images, you can use the 'bitmapdatapath' or the 'loadarray' functions. If these are JPEG2000 images, you will need lfj2k13n.dll which also requires that you purchase or JPEG2000 Plug-in. To save the file to memory, you can use the 'savememory' function.
