Without a doubt, it is the best extension for downloading images in Firefox, although there are not so many available. The good thing is that the configuration options cover all the possibilities of tracking and saving, or at least all the ones that I tested, and the filters are updated in real time of click. On the negative side, only the gallery section, which still lacks buttons for sorting type and size, a quantity display of selected items and, mainly, a method of selecting by clicking on the thumbnails instead of the check boxes, which are tiny and make operations with a lot of clicks very tiring.

awesome...

can i save image of multi tab?

Shows 1073 images on page, only downloads 275 of them. However, it has a nice interface and is working good enough.

Trying to exclude small images <320 width AND <240 height. But for example 350x150 are downloading.
Please, make different settings - AND/OR for each dimension. Tick changer - AND/OR will do fine.

-------- Tip For Other Chinese Users --------
非常不错，但你得有一点英文基础，至少得能看懂选项写的是啥对不？不懂的听我解释一下。

最上面的一排：左边一列是筛选文件大小，中间一列是筛选图片大小，右边一列是筛选图片文件格式。注意：只有勾选了标题处的复选框才会生效。

中间的四个区域：对于新手影响不大，保持默认就行

下面的［Save In］是保存的位置和文件名，默认保存位置是在［下载/网站域名/］这个文件夹，勾选［Save Dialog］则在下载完成后弹出浏览器的保存对话框自行选择保存位置。

最底下［Preferences］是一些附加设置，比如图片多于30张就向你确认啦什么的，只要你不丧(gan)心(de)病(piao)狂(liang)地使用一般也用不到。

------- ADVICE FOR THE DEVELOPOR(S) --------
Finally cames my ADVICE FOR THE DEVELOPOR(S), it seems not be able to remember my Save-In-Path automatically, it just use the host name for the saving folder name, that's too messy. I want it to remember my own Save-In-Path and apply it to all websites I visit. If I saved my zip-file in one path this time, I want to save all zip-files in this path from now on. I hope your improvement.
