Here's the code:

 33 p=0
 34 while True:
 35     p += 1
 36     time.sleep(2)
 37     try:
 38         search = imgur_client.gallery_search('cat', window='all', sort='time', page=p)
 39         for i in range(0, len(search)):
 40             item_count +=1 
 41             print(search[i].comment_count)
 42             if not search[i].is_album:
 43                 print(search[i].type) 
 44             print('{0}: {1}'.format("page number is", p))
 45             if search[i].comment_count > 10 and not search[i].is_album:
 46                 if search[i].type[6:] in image_type:
 47                     count = 0
 48                     try:
 49                         image_file = urllib2.urlopen(search[i].link, timeout = 5)
 50                         image_file_name = 'images/'+ search[i].id+'.'+search[i].type[6:]
 51                         output_image = open(image_file_name, 'wb') 
 52                         output_image.write(image_file.read())
 53                         for post in imgur_client.gallery_item_comments(search[i].id, sort='best'):
 54                             if count <= 10:
 55                                 count += 1
 56                         output_image.close()
 57                     except urllib2.URLError as e:
 58                         print(e)
 59                         continue
 60                     except socket.timeout as e:
 61                         print(e)
 62                         continue
 63                     except socket.error as e:
 64                         print(e)
 65                         continue
 66     except ImgurClientError as e:
 67         print(e)
 68         continue

Also is there a better method than gallery_search() in a page by page fashion? How can I browse the most popular items over all the time?
