Playing around with the images on Comic Strip Generator, I searched for the pages with titles beginning with the letter L. The only image with library in the title was an old fashioned man carrying a teetering pile of books. I filled in the dialogue balloon with a positive comment about being a student library assistant. I plan to tweak the brochure I give prospective student library assistants, putting the image at the top of the front.
I followed directions at the site to post the image to my blog, wrote my post and sent it. However, as sometimes happens with technology, I got an error message that an internal error prevented the successful completion of my post. As Charlie Brown says, "Sigh....." So, I have copied the link below.
Here is the link to the image: http://img300.imageshack.us/img300/8771/leftii5.jpg
Since I give responsibility for many displays to my students, I can see how they can use these online image generators to make attention-getting signs for events, book displays on themes, etc. Humorous graphic signs with gentle reminders about restrictions on cell phone use and gum chewing may be more effective than verbal reminders. The possibilities are only as limited as our imaginations.
