AppGini Community Forums

Ahmad,

This one's for you. Hope you can let us know a little more about how images are processed once they are uploaded through the AppGini generated web application into a field designated "image". Here's what I have deduced so far. Please let me know if my observations are accurate...

• Any file uploaded through AppGini gets stored in /images/ folder of the application on the web server.
• Files are given a name like : 92115000_1371070033.png.
• All stored files are follow the original format (ie jpgs getloaded as jpg, pngs as png etc)
• 92115000_1371070033.png is the original size version.
• Another version with a _dv.png suffix is saved with a smaller image size.
• Yet smaller version with _tv.png is saved. This must be the thumbnail view for list screens.

Can you kindly say yes or no next to each of my observations?

Finally.... Will the AppGini generated image file name (ie 92115000_1371070033.png) always remain in this format? ie 8char + underscore + 10char + dot + png. Can I rely on this to be the fixed name formatting?

Thanks so much!!!

Your guesses are correct .. I just want to clarify the last 2 points:
*_dv is the thumbnail version for the detail view
*_tv is the thumbnail version for the table view

The sizes for the _dv and _tv thumbnails are determined in the "image options" dialog in AppGini .. so the _tv version is not necessarily smaller than the _dv one.

You can depend on this naming scheme to persist, unless you check the option "Don't rename uploaded files". In future versions, I plan to make the storage location and naming scheme more controllable in AppGini, and to add support to cloud storage, like Amazon S3 .. etc. But the current behavior would still be one of the options available.

Ahmad,

This sounds great. Thanks much for the explanation. Most appreciated.

Ahmad, sorry for dragging an old post but I think the next question is relevant...

I'm setting up an AppGini app on a baremetal server running on Digital Ocean. Server has LAMP running but somehow the thumbnail creation is not working. I am guessing an image processing library used by AppGini is not installed on my server. Can you kindly outline the required libraries and versions which I need to install & verify?

Thanks much!!!

Try installing the gd library .. On ubuntu, the command is: then restart Apache:

Dear Ahmad, this worked like a charm!!! Thank you so very much for your response. Most appreciated.
