如何使用「图片转拍立得相框」？How do I use the Convert Image to Polaroid tool?
在「图片转拍立得相框」中，选择或拖入文件，按需设置「边框宽度 (px)」、「底边高度 (px)」、「边框颜色」、「标题（可选）」、「标题字号」等选项，然后点击每个结果旁的「下载」按钮即可；有多个文件时也可以点「全部下载（ZIP）」一次打包下载。Choose or drop one or more images, then set the "Border width (px)", the taller "Bottom strip (px)", the "Frame colour", an optional "Caption" with its "Caption size", and the output "Format". Each framed image gets its own Download button, and "Download all (ZIP)" saves them together.
边框颜色能改成黑色吗？Can the frame be black?
可以，用“边框颜色”选任意颜色；经典拍立得是白色，深色边框更像宝丽来相纸背面。Yes — pick any colour with Frame colour. Classic Polaroids are white; a dark frame looks more like the back of Polaroid film.
标题太长会怎样？What if the caption is too long?
会自动截断并加上省略号，保证不超出底边空白；也可以把底边高度调大或字号调小。标题颜色会按边框深浅自动选深灰或浅灰，深色边框上也看得清。It is truncated with an ellipsis so it stays inside the bottom strip; you can also make the strip taller or the caption smaller. The caption is dark grey on light frames and light grey on dark frames, so it stays readable.
数值范围是多少？What are the allowed values?
边框宽度 4–200 px，底边高度 0–400 px，标题字号 8–72 px，都须为整数；留空、负数、小数或超出范围会给出明确提示，不会悄悄改成别的值。Border width 4–200 px, bottom strip 0–400 px, caption size 8–72 px, all whole numbers. Blank, negative, decimal or out-of-range values show a clear message instead of being silently changed.
