Since you have enabled the `static_html_cache` plugin you really should have no performance issues. That plugin will cache each page the first time it is viewed (by a visitor) and then serve it from the cache thereafter. At that point the page is just simple HTML, so if there is still a problem it is with your server or network connection.

It is possible that the HTML cache has captured the page before the images have been cached. If so you can just purge the HTML cache and things will be fine.

You should be able to disable the `deprecated-functions` plugin but that will not make much difference.

Thanks Stephen,

To be more precise, randomly some thumbnails does not appears and after comeback.

That seems to be a cache problem, no ?

If you have cleared your caches it takes some processing to get things re-cached. If the serving of the image takes too long, the browser shows the missing image display. If the page with those missing images is cached it will probably never catch up as it will use the image generator each time.

Probably the HTML cache should not be caching pages during this period of time, that will be implemented on the 1.4.3 release as it is too late for that kind of change in 1.4.2.

In the mean time, leave the HTML cache plugin disabled until all your thumbnails are being shown.

OK Stephen.
Thanks again.
