Speaking of storage, the frame itself sports a fairly meagre 64MB of flash memory. However, it supports SD, SDHC, MMC, xD, CF, MS and MS Pro cards so you'll have no problem getting your pictures to display, be that directly from a camera or transferred from a PC. If you are happy just to use the internal capacity then you'll need to use the built-in USB to mini-USB cable.
We've established, then, that getting pictures onto the TekBright Photo Frame is a simple enough affair, but getting them into a viewable state is a different matter altogether. The long and short of the issue is that unless you have your photos cropped and resized to the native 720 x 480 resolution of the panel they won't display correctly but will instead be cropped to the bottom right hand corner. No prizes there then.
Common sense would suggest, though, that the majority of users aren't likely to change what photos they wish to have on the frame. Thus, the few minutes effort required to edit shouldn't pose too frequent an annoyance. In terms of formats, the frame will support either JPEG or Bitmaps only, but realistically the former is likely to be the only one ever likely to be wanted.
As a curious addition, found hidden at the rear is a small speaker. Further inspection reveals that the frame has a special "Music" mode whereby you can accompany your slideshows with a whopping 1W of tinny, strained music. Yes, that might sound a tad harsh, but the audio reproduction is nothing short of shockingly bad at anything other than what is best described as "lift music". Arguably that is exactly the kind of audio accompaniment that a picture frame would want to be producing anyway, but in all honesty Toshiba would almost definitely have been better off knocking a few quid off the asking price and saving itself the effort.
Making up for that shortcoming is the navigation and interface on the TekBright. While I've never been a big fan of touch-sensitive buttons, Toshiba's use of them in this case isn't nearly the profanity-inducing experience initially expected. These buttons are located on the lower front bezel of the frame and are illuminated in a pleasing blue from behind. However, after a short period without use this lighting will turn off, the buttons then require a single tap to be reactivated. It's a simple feature but a pleasing one.
