It is not necessary to be signed in to have the pictures enlarge.  Let's troubleshoot.
Most common issues:

• Be sure POP Ups are allowed for GunsInternational.com.  Internet Explorer: Tools to Pop Up Blocker , click turn off po up blocker.  Mozilla Firefox:  Tools to Content make sure there is no check on pop up blocker and then click OK.
• If you have clicked to open a listing and then clicked the thumbnail photos in the individual listing and the photos are not enlarging it may be one of a few issues 1. The photo opens in a second window, look down at your bottom bar of your screen, do you see another window that is downsized, if so click on it and you will see the photo. You may have failed to close the photo window before.  Once a photo is enlarged within the listing, you may continue to click on that photo and it will cycle through all the photos on that listing within the same enlarged window.  You do not need to close the window and then open the next photo and so on. 

 
Here are some further issues that may be preventing you from viewing the enlarged photos on GunsInternational.com:
1.. You may have too many processes running on your computer and therefore your PC is out of memory.  Close down other programs that are running.

2  Another issue that can come into play regarding photos has to do with those who have Kaspersky Anti-Virus.  For some reason even though you are instructing the picture window to open, Kaspersky views the enlargement as a pop up. If you have Kaspersky Anti-Virus then you need to go into the settings and allow pop ups for GunsInternational.com.
