After I upgraded from v2.2.1 to v2.2.4, now I cant seemed to upload photos into the module My Album v2.84. Previously it was working fine.

Errors Returned While Uploading
Failed uploading file: photo.jpg

Then, updated to the latest 2.90beta, still failed. What could have happened? Kindly help!

It sounds odd.
Anyway, check .htaccess, or permissions of each photo's directory.

Or, go to "check configs&environments" in preferences of myAlbum-P

here's the result on the check configs&environments

Environment Check
PHP directive 'safe_mode' (both ok): off
PHP directive 'file_uploads' (need on): on
PHP directive 'register_globals' (both ok): on
PHP directive 'upload_max_filesize': 20M byte
PHP directive 'post_max_size': 8M byte
PHP directive 'open_basedir': nothing
PHP directive 'upload_tmp_dir': ok c:/php/uploadtemp
Table Check
Photos table: xoops_myalbum_photos ok
Number of Photos: 11

Descriptions table: xoops_myalbum_text ok
Number of Descriptions: 11

Categories table: xoops_myalbum_cat ok
Number of Categories: 9

Votedata table: xoops_myalbum_votedata ok
Number of Votedata: 0

Comments table: xoops_xoopscomments ok
Number of Comments: 0

Config Check
Pipe for images: GD
GD Version: bundled (2.0.28 compatible)
Check that 'GD2'is working correctly under your GD bundled with PHP
If the page linked to from here doesn't display correctly, you should not use your GD in truecolor mode.

Directory for Photos: C:/Domains/wongloong.net/wwwroot/uploads/photos ok

Photos & Thumbs Link Check
Now, checking .. . . . . . . . . . . ok


and the .htaccess.dist:
php_flag register_globals Off
php_flag allow_url_fopen Off

hmm.
I guess the picture is bigger than settings.
