First off, before my rant please let me say that this NAS is a top piece of kit. The following is only a minor gripe likely experienced by lots of people in their first few days!
I wont claim to be a guru on the way you've programmed the Photo Uploader within Synology Assistant but it seems awfully inefficient.
The current method seems to process each photo at a time, something like:
Create Thumb using convert
Upload photo+thumb using a php script!!!
Note: using the php function of photostation for a batch upload is not good! Whats the need for the file in /photo/@edDir/ASST_PHOTO_UPLOAD_TMP_DIR/ASST_TMP_* ?
Would it not be more efficient to simply batch process the entire collection of photos for processing and then upload the photos to the /photo area and then the thumbnails to where ever they are stored within the filesystem via a proper file transfer protocol (oh wait... isnt that what FTP is for!)
Dont get me wrong, i've only had the DS for 2 days and think it's a great piece of kit, it provides so much more than what other NAS sellers give. I applaud the use of linux, it seems to be implemented well and the system seems pretty secure. (I'll be performing security testing in my own time against my box - anything i find i'll disclose in the correct manner).
Cheers again but please sort this out
(or provide me with more info on the photostation file storage so that i can manually create the thumbnails and upload that way - bash scripting all the way!)
