Lightroom: Improve Flickr publish robustness by pre-checking the file size before sending to Flickr

When publishing a set of photographs to Flickr, the API sometimes returns an error relating to the jpg version of the file being too large. It appears that the error is only detected afters some considerable time towards the end of the transfer when the amount of data sent for the image has reached the users max file size limit.
This is wasteful of the user’s time and bandwidth and possibly the source of some consternation to some users.

I suspect that the publish service could use the Flickr api call “flickr.people.getUploadStatus” to establish the users max file size at the start of a publish cycle and then error an upload to Flickr prior to simply throwing the jpg image at Flickr to find out if it is too large. This could provide a more robust user friendly UI.

PS – I generally send my images at 100% jpg quality and only temporarily reduce it if a particular image exceeds my size allowance.

Don't use 100% for web use. You won't even notice.

Thanks John ... I am aware of that, but even though I have a fairly robust DR system it provides me with some comfort that some of my favourite images are in the cloud storage at best quality possible.

My point however remains the same,the process could be made more robust by a simple pre-check by LR using the Flickr api. I appreciate I could set the file size limit on the publish settings but I have not yet gained confidence that this (as it should) makes no additional reduction in IQ if the rendered jpg is below that threshold - I am just about to do some testing on this aspect. Even with that I think it would still be worth what I (although un-informed) see as a simple bit of precheck code in the plugin.

I know this is not central to my point anyway ... but as a follow up - if I set an export file size limit of circa 20MB and export 72 files of varying size, all of which are significantly less than this limit at full IQ export, then all files are reduced in size v's an export with no limit.

For example a file which is exported without size restriction at 100% is only 472KB but with the 20MB llimit the same file comes out at 449KB.

Once again ... I stress this is incidental to my point -

It would be prudent for the the publishing plugin to check the file size before simply throwing it at Flickr.
